State Route 110 was a proposed semi-loop highway around Tucson. Its proposed route would've ran along Grant Rd from I-10 Exit 256, past Tanque Verde Rd, where Grant becomes Kolb Rd to I-10 Exit 270. The only trace of this route that I've been able to find is an entry for it in the 1996-1999 ADOT State Highway System logs, which doesn't have much info. In 2000, SR 110 disappeared from the SHS log.
